Method Exit bag and inert gas megathread

I guess the part that goes over the nose/mouth is more like a respirator.
From the photos that part looks like it is more than just a hose to a face/mouth covering.
So I assume these EEBD hood are a constant flow into the hood ?

Is the one u are referring to,a hard full face or head model?

Most EEBD are constant flow .

I found SCOTT had various EEBD models when searching for one to get.
I purposely got EEBD rather than SCBA because I wasnt sure that low force unconscious breathing would engage valve on LDV of SCBA.
(This is just my observations, I'm not sure if its correct since ppl here have used SCBA).
Positive pressure environment would be easier to breathe I think.(again,just my thoughts).
Scott makes 'Rescue hoods' as well ,which looks similar to EEBD but differ in mechanical make-up ,max flow rate etc.
Buying any of these 2nd hand are a lot cheaper ,however u will most likely receive 1 thats-
Over 10 years old(EEBD replacement period for Industry etc) .
Stiff neck seal,elastic due to age,Storage.
Exhaust valve may stick open if correct lubrication wasn't applied to spring during servicing.

I purchased used ELSA initially but then purchased brand new.
